  I have ad adsl 4mbit connection that sometimes has bandwidth problems and behaves like a 56k or less.
  In these moments when I try to load pages, firefox eats 10% of the cpu and Xorg 50%, and the processor speed is maxed to 100% (1.6 Ghz), while waiting for packets to arrive (I think it does ad active wait).
  This lasts when the page is completely loaded: sometimes 2-3 minutes of heavy load!
  
  This is always reproducible, only if the tab is which is loading is
  selected. When it is deselected the cpu is no more used!
